How much can you get outrebounded by and still win?

Texas A&M outrebounds Dayton 47-26 but the Flyers beat the Aggies 55-53 in the First Round of the Puerto Rico Tip-Off tournament. Any way to find out the record for being outrebounded the most yet still winning? I asked Ken Pomeroy but it’s not something he’s done. My guess is 21 is not the record but it would be interesting to know what is.
